Managing triax cable routing and attachment on a Steadicam rig to minimize interference with sled movement

21 years old. Gear and prices may have changed since.

What the thread found

  • The cable should be secured at multiple points along its length, particularly close to the gimbal and center of gravity, to reduce its ability to affect sled movement and rotation.
  • Routing the cable up and over the shoulder, then down the back of the vest, with a loop hanging to knee level reduces lateral pulling forces on the sled.
  • The cable should be secured near the gimbal mount and post junction, leaving appropriate slack to allow smooth sled rotation without the cable weight pulling the sled in one direction.
  • Using thinner, more flexible triax cable or lightweight alternatives reduces negative effects on sled dynamics and makes quick disconnection easier.
  • An alternative approach involves adapting thick triax to coaxial cable with barrel connectors for the operator-side segment, allowing use of flexible coaxial cable from camera to vest while maintaining triax connection to the truck.
  • Securing the cable at the battery rack beneath the center post prevents lateral pulling while forming a long vertical loop minimizes side tension.
  • Wireless camera systems eliminate cable-related sled interference entirely.
  • Cutting or stripping triax cable shielding is unsafe due to high voltage present in the cable and creates fire and shock hazards.

Depends on

  • These solutions apply primarily to triax-equipped broadcast camera systems; techniques may differ for other cable types.
  • Some production engineers and facility managers prohibit the use of cable adapters due to concerns about damage to base stations or camera equipment.
  • Wireless systems represent a significant capital investment and availability depends on production budget and equipment rental access.
  • The effectiveness of any cable routing strategy depends on operator skill and consistency in managing cable placement during movement.
  • Thinner triax cable options may have reduced durability compared to standard gauge cables.
